Abstract

Abstract:

In Alashan area，Inner Mongolia Autonomous Region，the Hulunxibai gold deposit locates in the inner and outer contact belts of Hulunxibai granite．The ore boods are controlled by the zones of fracturs，and consist of altered disseminated ore bodies and Au-bearing quartz vein lens．By single zircon U-Pb and quartz ⁴⁰Ar／³⁹Ar methods，the ages of Au-bearing quanz vein were directly detected．The results shown that themetallogenic epoch of Hulunxibai gold deposit is 319.5 Ma to 348.84 Ma，that is middle Variscan period．

Key words: metallogenic age, Hulunxibai gold deposit, Alashan area of Inner Mongolia Autonomous Region
